Supply heat to hair wound upon the usual spool, the device is first positioned over the spool and then the sections moved laterally one towards the other. their innermost position this position by engagement of extension or tab 4.0 with the 4.opening 39 inthe spring 38 since the normal movement of this spring is upward. After the desired` amount ofheat has been applied to the hair, the heater may be removed by depressing spring 38 (the end of which extends'beyond the surface of handle 36) thereby disengaging thetab 40 from openin 39 and permitting the spring 37 to force t e sections apart.

It will be evident from the foregoing that the heater of the present invention is one WhenV they reach they are locked in which is simple and inexpensive to manufacl ture which may be readily applied to or removed from hair wrapped around a spool and'which is otherwise eiiicient in operation.

It is to be understood that the invention is not to be limited to the illustrated embodiment but is to be limited only by the scope of the following claims.

I claim: 1. A heating` device of the character described comprising a pair of arcuate shaped heater sections connected together for uniform rectilinear movement.

2. A heating device of the character described comprising a pair of arcuate shaped heater members, means connectin said members together at the tops thereof rectilinear .movement toward and away from each other.

3..A heating device of the character described comprising a pair of arcuate shaped heater sections, means connecting said sections together at the'tops thereof for unif0rm rectilinear movement and resilient means for forcing said sections apart.
